The polarized layer 223 is disposedadjacent to the liquid crystal layer 23. The color layer 222 includes ablue light filter layer 224 and the color unit layer 225. The color unitlayer includes several color unit (not marked), each color unit includesa red quantum rod layer (R) 226, a green quantum rod layer (G) 227 and atransparent color filter layer (T) 228, where the red quantum rod layer226 and the green quantum rod layer 227 are stacked on the blue lightfilter layer 224 and the major axis direction of the red quantum rodlayer 226 and the green quantum rod layer 227 are perpendicular to thelight direction of the backlight module 10.

In this embodiment, the LCD device further comprises a plastic box, andthe plastic box is located between the color film substrate 21 and thearray substrate 22 and seals the liquid crystal layer 23. The color filmsubstrate 21 opposite to the surface of the liquid crystal layer 23 isequipped with a polarizer 211. The array substrate 22 includes analignment layer (not shown) and a drive array unit layer 220. The drivearray unit layer 220 is placed on the glass substrate.

In the LCD device of the present invention, the color layer 222 isequivalent to the pixel layer in the LCD panel. The quantum rod is usedinstead of the traditional color pixel filter chip structure. Since thelight-emitting properties of the quantum rod and quantum dots hassimilar characteristics, Its emission spectrum of the wavelength can beadjusted through the quantum rod diameter, and when the blue light(either natural light or polarized light) is excited by the quantum rodemitting light, the quantum rod emits the polarized light. The backlightmodule light source is blue light, so the quantum rod is used as colorlayer for LCD device of the present invention to avoid the differentcolors absorbing light source from each other between the color layers.It can be relatively significant reduction in the conventional liquidcrystal display light energy consumption, while the high colorsaturation of the screen increases.
